Trust me, ImageDuel is extremely addicting, and I’m not the only one who thinks so. Since launching the site in April 2011, Pixoto has already had 440,840 images submitted and an astounding 18,815,635 votes polled according to the sidebar on their site. Pixoto is now up to 40,000 total members according to their Angel List profile update.

Of course, the one issue Pixoto is facing is the copyright issues that all photographers are facing online right now. It is just way too easy for people to Pin these images on Pinterest, so some photographers might not be comfortable submitting their photos quiet so easily. Nevertheless, photographers are still submitting photos, so that’s clearly not stopping Pixoto from succeeding.
